IMPROVEMENT IN MEANS FOR REMOVING AND DESTROYING SEWER-GASES.

Specification forming part of Letters Patent No. 198,271, dated December18, 1877 application filed August 30, 1877.

To all whom it may concern:

Be it known that I, SAMUEL J. OoRBETT, of the city and county of LosAngeles, and State of California, have invented a Device for Removingand Destroying Sewer-Gases; and I do hereby declare the following to bea full, clear, and exact description thereof, reference being had to theaccompanying drawings.

My invention relates to a novel method for destroying such noxious casesas are generated in the sewers of a city; and it consists in leading apipe from the sewer to each of the gas-lights along its line, so thatthe gases will be conducted to and delivered into the flames, andthereby destroyed.

My plan is intended not only to provide a vent through which these gasescan pass to the open air in the day-time as fast as they accumulate, butwhen the gas is lighted at night each gas-jet establishes a draftthrough the gas or vent tube, which draws the gases into the flame,where it is destroyed, thus preventing any accumulation of gas in thesewer.

Referring to the accompanying drawing, the figure represents a verticalsection of a lamppost and longitudinal section of a sewer.

Let A represent the level of a street-surface; B, a sewer; C, alamp-post; D, the gas-main;

- E, the gas-pipe which leads to the lamp, and

F the pipe extending from the sewer to the gas-burner. I shall usuallylead this pipe up inside of the lamp-post, and will construct a shieldor bonnet, G, around the gas-burner, so

i that the upper end of the pipe F will terminate inside of it. Thiscompels the gas which escapes from the upper end of the pipe F to comein contact with the flame of the gas-burner, whereby it is burned anddestroyed.

Ifdesired, a cock can be applied near the upper end of the pipe F, whichcan be closed in day-time, so as to prevent the escape of the gas whenthe gas-light is not burning; but when the gas is lighted this cock mustbe opened, so that the draft which is occasioned by the heat of thegas-flame will draw off the gases from the sewer and burn them.

The small quantity of gas which is drawn off from the sewer at a timewill prevent any deleterious effects upon the gas-flame, even if the gasis non-inflammable.

By this arrangement I can prevent any accumulation of gas in the sewer,and by providing a vent the liability of this foul gas escaping at anyother point is avoided.

I am aware that consuming the gases generated in sewers by drawing andforcing them through a super-heating furnace or chamber is old, and suchI do not claim as my invention; but

Iiaving thus described my invention, what I claim, and desire to secureby Letters Patent, is-

The gas-pipe E, provided with a shield or bonnet, G, in combination withthe pipe F, the lower end of which connects with the interior of thesewer B, while its upper end terminates inside of the shield,substantially as and for the purpose described.

In witness whereof I have hereunto set my hand and seal.
